ARIADNE is a European foundation that aims to foster “Share and Reuse” of learning resources. To support this goal, ARIADNE
has created an infrastructure for managing learning objects in an open and scalable way. This paper describes the technical
approach behind our open, standards based infrastructure, how content providers can connect to it, and the value they can
derive from doing so. As such, the abundance that we help to unlock will act as a platform for innovation by tool developers,
trainers and teachers and learners themselves.
"In addition, learning resource exchanges often have different goals than that of teacher resource exchanges. For example, learning resource systems such as MERLOT (Li 2010), ARIADNE (Klerkx et al. 2010), Connexions (Dholakia et al. 2006), and OER Commons (About OER Commons 2013) are designed to be forums where many different types of educators can exchange a wide variety of online learning resources. This object type diversity necessitates the use of standards that are complex. "
[Show abstract][Hide abstract] ABSTRACT: A large-scale online teacher resource exchange is studied to examine the ways in which metadata influence teachers’ selection of resources. A hierarchical linear modeling approach was used to tease apart the simultaneous effects of resource features and author features. From a decision heuristics theoretical perspective, teachers appear to rely on complex heuristics that integrate many dimensions when determining whether to download a resource. Most surprisingly, numbers of ratings more strongly predict downloads than do mean rating levels, such that multiple negative ratings appear to attract more downloads than do few positive ratings. Implications for system design are discussed.

[Show abstract][Hide abstract] ABSTRACT: Despite the existence of numerous standards and specifications in technology-enhanced learning, there is a lack of interoperability of artifacts and services throughout the whole lifecycle of outcome-based education. In this pa-per we present the concept and prototypical implementation of an open archi-tecture that aims to remedy these issues by providing a unified metadata and service layer for making key educational resources sharable, storable, findable, and interoperable. The reference model and its supporting technology architec-ture are tested by a family of prototypes implemented as extensions to or adap-tations of existing mainstream systems like Moodle, .LRN, Elgg and Facebook.
